Chamber Safe
Chamber Safe is a UL Listed high performance, refractory parging material designed to strengthen, streamline, and restore the critical smoke chamber area in masonry chimneys. The preferred choice of chimney professionals, Chamber Safe smooths jagged, corbelled walls typically found in the smoke chamber, and creates a smooth transition between the smoke chamber, and flue liner. Chamber Safe is the ideal choice for improving the flow or draft of the fireplace! The unique insulating properties of our Chamber Safe product improves the safety of the chimney by reducing radiant heat transfer through the smoke chamber. Chamber Safe can be installed by cast, parge, trowel, hand pack or grout bag method. This product meets ASTM standards (E-196, C199, & C401), and is non-water soluble.
Chamber Safe Can Repair:

Superior Product
by Chris R - London Chimney -
My technicians have reported that the Chamber Safe is much easier to apply and gives a smoother application than Chambertech 2000
Great product
by Mason D Shull
Product mixes and applies easily creating in effect a uniform liner for the smoke chamber that seals any voids or damage, After application there is a marked increase in chimney draft.
So easy!
by Mark Miller
Easy to use, goes on smooth and hasn't cracked on me yet. I get more bang for my buck because I have to use less as opposed to other products.

After seeing Chamber Safe in action at Lindemann U, I was sold! Love using the stuff now. My technicians save time in the field because they use less, and it sticks better.

Best Product for Chamber Parging!
by Jason R. Ward
Chamber safe is, in my opinion the best product for chamber parging. It offers supreme protection with ease of application. It is easy to work by hand and with trowel. The mess is less with chamber safe than any other product we have used. In the twenty plus years I have spent in masonry and chimney work I must say chamber safe is the very best!
